  • High quality for a resonable price

    This is a high-end PSU at a reasonable price. There are in-depth reviews with detailed testing available online (such as Tom's Hardware) for this power supply, and as of 2021, it is a known quality unit. I've only loaded this PSU up to maybe 50% load, and it is very quiet. I performed low-load efficiency tests with this PSU as well as two other PSUs I have on hand, the Corsair CX450M and TX550M. At 20 to 35 watts, it uses 6-10% less power than the CX450M, and 3-5% less power than the TX550M. The cables are quality, and all-black. The motherboard and CPU connectors are easier to connect and disconnect to a motherboard than some cheaper PSUs I have tested. The PSU and its cables have a very clean look. I would have liked to see a additional slot for another PCI-e cable, but it is only a 550W unit. The 10 year warranty is great, but it only applies to the original purchaser of the product, unlike EVGA's power supply warranties.
